Perhaps you should try some spelling variations:
"sociologist" » "sociological"
"sociologists" » "sociologicals", "sociological", "radiologists"
"sociologicals" » "sociological", "sociologically", "sociologicos"
"sociologicas" » "sociological", "sociologicos", "sociologica"
"sociologie" » "sociologia", "sociological"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("sociologist" OR (("sociologists" OR "biologists") OR ("sociologicals" OR "sociologicas"))) OR ("sociologie" OR "sociology")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"sociologist\" or ((\"sociologists\" or \"biologists\") or (\"sociologicals\" OR \"sociologicas\"))) or (\"sociologie\" or \"sociology\"))".
• Removing quotes may allow a broader search: (( sociologist or (( sociologists or biologists ) or ( sociologicals OR sociologicas ))) or ( sociologie or sociology )).
• Adding a wildcard symbol may retrieve word variants: (("sociologist" or (("sociologists" or "biologists") or ("sociologicals" OR "sociologicas"))) or ("sociologie" or "sociology"))*.
